sorry but i don't understand, i was reading also the octave manual but
how to pass a global variable to a function:

here i define a global varable A:

svx = (std(mat(3,:)))^2;
svy = (std(mat(4,:)))^2;
global A=(sqrt((svx+svy)/2))    

here i define the function and i try to pass the global variable A to
this function but probably there is a big mistake:
 
function y = f (x,A)  
y =(x/A**2)*exp(-x**2/(2*A**2)) ;
endfunction

but nothing. :(

thanks a lot
paolo
